Look up under the dash on the far ends and you will find plastic tubes that lead to the air vents. These tubes are NLA and sell for far more than you might imagine.

Also grab the blinker relay off the firewall. And the radio if it is still there.

Check for the power brake option. On the pre 1962 cars, and perhaps on some later ones, this booster is not on the firewall but up under the battery.

And if there is a Kuglefisher under dash air conditioner then any parts of it are worth something.
